Near its lower end said receptacle is provided with a d raw-ofi cock l 18, through which water and sediment may be drawn.

In operation the crude oil is placed in the upper tank or receptacle 1, where the water and heavier foreign matter will settle to the bottom of the receptacle. The cock 7 is now turned on, and the oil above the point of communication of pipe 4: will pass through said pipe and into the lower portion of the receptacle 3, where it will percolate or filter upwardly through the filtering material 13 and into the upper portion of the receptacle,where it overflows through the cock 17 into a suitable receptacle. The water and sediment which has settled in the bottom of the receptacles 1 and 3 may be drawn off when desired through the draw-ofi? cocks 9 and 18, as hereinbefore described.

\Vhen the receptacle 3 is swung to the position shown in Fig. 3, the leg or bar 8 will support the upper receptacle 1 on the one side and the receptacle 3, through the pipe 4, will support the same on the opposite side.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In an oil-filter, the combination with an upper settling tank or receptacle, of a lower filtering-tank arranged below said upper tank, a valved oil-conducting pipe, connected at its upper end to said settling-tank and at its lower end to said filtering-tank, a pivotal joint in said pipe to permit the lower tank to swing from beneath the upper tank, a filtering device arranged in said lowertank, said device consisting of a lower perforated plate or disk supported in said lower receptacle, a filtering medium arranged on said lower plate, an upper plate resting on said medium, a clampingframe or spider, the ends of the arms of which engage lugs fixed on the inner sides of said lower receptacle above said upper plate, and a clamping-screw mounted in said spider to engage said upper plate and force the same downwardly, thereby compressing said filtering material, substantially as described.

2. In an oil-filter, the combination with an upper settling tank or receptacle, of a lower filtering-tank, arranged below said upper tank, a valved oil-conducting pipe connected at its upper end to said settling-tank above the bottom of the same, an elbow connected to said lower tank above the bottom thereof, a packed gland or joint pivotally connecting the lower end of said pipe with said elbow, to permit said lower tank to be swung from beneath said upper tank, a leg for supporting said upper tank when the lower tank is swung from beneath it, a filtering device arranged in said lower tank, an overflow-cock arranged in the latter above said filtering device, and draw-off cocks arranged near the lower ends of said upper and lower tanks, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
